Grant Baker Posted June 17, 2020 Report Share Posted June 17, 2020 Hi Guys, Does anybody have any information on this coil: It's from an E46 M3. 0221504464 Just wondering if it can be directly driven from the Link Ignition drivers, and if wiring information is available! Thanks Quote Link to comment Share on other sites More sharing options...
Rossobianconero Posted June 17, 2020 Report Share Posted June 17, 2020 We wire a e46 m3 engine, and the stock ignition coil is a dump coil, so you will need a igniter module on the wiring. It was a US market m3, I dont know if have any difference with other markets. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted June 17, 2020 Report Share Posted June 17, 2020 How many pins does it have? You can typically figure out if it has an internal igniter based on the number of pins and by measuring the resistance between certain pins. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 18, 2020 Report Share Posted June 18, 2020 Yes they are a dumb coil, you will need an ignitor. The pin marked "GND" in the pic below is the secondary winding ground, this should ground on the cyl head, the other two +/- pins are the primary.
